Introduced two new syscalls for controlling the kernel's behaviour on new
device detection, and began work on the kernel infrastructure for in-kernel
driver udi_init_t structures.

* New floodplainn syscalls:
  ^ setNewDeviceAction: Tells the kernel what to do when new devices are
    detected. Do nothing, detect a driver and stop, detect and load a driver
    and stop, or instantiate fully.
  ^ getNewDeviceAction: Asks the kernel what its current behaviour for new
    device detection is.
* Added comments to detectDriver.
* Fixed some problems in the UDI includes from UDIRef.
